rtc_stats: Update code to remove chromium style warnings suppression.
The warning previously suppressed made it possible to define tings like
constructors in the header, and "complex" objects did not need to have
an explicit out-of-line copy constructor, destructor, etc.
To be able to not suppress this warning, the RTCStats macro was split
into a WEBRTC_RTCSTATS_DECL() and WEBRTC_RTCSTATS_IMPL() for .h and .cc
respectively. Some copy constructors are also defined.
